Title: Process for recovery of metals from used nickel-metal hydride storage batteries
Inventor: KOHLER UWE
IPC: H01M6/52
Filed: 1995-12-01
Granted: 2006-10-10
Abstract: In the recycling of used nickel/metal hydride storage batteries, the battery scrap is dissolved in sulphuric acid after mechanical separation of the coarse constituents by magnetic and air separation. A solvent extraction is performed with the digestion solution, from which the rare earths (from the hydrogen-storage alloys in the negative electrodes) and iron and aluminium have been selected by precipitation, under conditions (ph [sic], choice of solvent, volumetric ratio of the phases) which are such that the aqueous phase contains nickel and cobalt in the same atomic ratio as that in which they were present in the scrap. This makes possible a joint recovery by simultaneous electrolysis, in which process the deposition product forms a master alloy which can be used, together with the precipitated rare earths which have been electrometallurgically reprocessed as mixed metal, for the production of fresh hydrogen-storage alloys.

Granted: 2006-06-06
Abstract: An intravascular device for the formation of linear lesions which has particular utility in the treatment of atrial fibrillation and flutter. The intravascular device has an outer delivery sheath (11) with a distal section (25) which has an elongated opening (28) and a support member (26) coextending with the opening (28). An EP device (12) having a plurality of electrodes (32) on its distal portion (31) is slidably disposed within the inner lumen (13) of the delivery sheath (11) but it is secured by its distal end within the distal extremity of the delivery sheath (11) at least while in operation. In this manner an axial force in the distal direction on the proximal extremity of the EP device (12), which extends out of the patient during the procedure, will cause the distal portion of the EP device (12) to arch outwardly out of and away from the distal section (25) of the delivery sheath (11) and engage the surface of the patient's heart chamber. High frequency, e.g. RF, electrical energy delivered to the electrodes (32) on the distal shaft section (31) of the EP device (12) will form a linear lesion which terminates the fibrillation or flutter.

IPC: C07K1/13
Filed: 1997-07-08
Granted: 2009-06-30
Abstract: A method of labelling molecules which includes providing in a common medium a label molecule, a marker ligand able to bind a member of a specific bind-ing pair, such as an antigen, a sbp mem-ber, an enzyme able to catalyse binding of the label molecule to other molecules, the enzyme being associated with the marker ligand; causing or allowing binding of the marker ligand to the sbp member, and causing or allowing binding of the label molecule to other molecules in the vicin-ity of the marker ligand bound to the sbp member. The marker ligand may be an antibody or any specific binding molecule, such as a chemokine or cytokine. A com-plementary member of the specific bind-ing pair may be included, e.g. an an-tibody, or a diverse population of such sbp members, e.g. antibodies, may be included within which those which bind the counterpart sbp member, e.g. antigen, may be labelled and subsequently isolated for manipulation and/or use. Suitable la-bels include biotin-tyramine with signal transfer being catalysed by hydrogen per-oxidase. Cells, virus particles and other moieties may be labelled, for identifica-tion or obtention of proteins which inter-act or are in close proximity with a particular sbp member, or of cells of interest, or for enhancement of labelling, e.g. for cell sorting.

Abstract: A burner (40) having a transition zone (46) to act as a buffer between the primary zone (42) and the secondary zones (48, 50). The transition zone (46) allows improved control of near-burner mixing and flame stability by providing limited recirculation regions between the primary zone (42) and the secondary zones (48, 50). These limited recirculation regions transport evolved NO x back towards an oxygen-lean pyrolysis zone near the burner exit (52) for reduction to molecular nitrogen, thus decreasing emissions and unburned fuel losses.
